知识点拨
1. 虚拟语气在if条件句的应用
|if条件句|从句的谓语形式|主句的谓语形式|
|表示现在|动词过去式(be的过去式用were)|should/would/could/might＋动词原形|
|表示过去|had＋过去分词|should/would/could/might＋have＋过去分词|
|表示将来|should＋动词原形/were to＋动词原形|should/would/could/might＋动词原形|
2. 错综条件句：主句与从句动词发生时间不一致，动词形式要根据发生时间作出相应调整。
3. if省略句：含有had/were/should的虚拟条件句中省略if，将had/were/should放在主语之前。
4. 含蓄条件句：假设条件隐含在词或短语或上下文，有：without, in case,but for, otherwise等 。
